When VSync is disabled, the engine runs at unlimited FPS which wastes GPU resources and power. Add a configurable FPS cap (e.g., via AppSettings::fps_limit) that works independently of VSync.

Acceptance criteria:

New field in AppSettings (e.g., fps_limit: Option<u64>)
When set, the frame loop sleeps/delays to match the target FPS
Should not interfere with VSync when both are enabled
Test with both AutoVsync and AutoNoVsync present modes

When VSync is disabled, the engine runs at unlimited FPS which wastes GPU resources and power. Add a configurable FPS cap (e.g., via `AppSettings::fps_limit`) that works independently of VSync. **Acceptance criteria:** - New field in `AppSettings` (e.g., `fps_limit: Option<u64>`) - When set, the frame loop sleeps/delays to match the target FPS - Should not interfere with VSync when both are enabled - Test with both `AutoVsync` and `AutoNoVsync` present modes
